Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.

Time flies when you're learning super cool stuff.

I'm Nate.

And I'm Callie. If you're dropping in for the first time,

welcome to curiosity where we aim to blow your mind by helping you to grow your mind. If you're

a loyal listener, welcome back. Today you'll learn about a new way to turn salt water into drinking water.

Research that suggests stuffing your bad feelings deep down might actually be a good thing.

And an amazing 500,000 year old discovery in Tanzania.

Without further ado, let's satisfy some curiosity.

Scientists have developed a new way to desolinate sea water that requires less electricity than current methods.

And that could be a real game changer for people living in drought-stricken regions where energy sources are limited.

I think we have talked a little bit about water desalination on the show before and if memory serves it's a massively

expensive process that uses enormous amounts of energy right?

Pretty much. There are a few ways to gank the salt out of sea water to make it safe to consume.

There's distillation, the oldest method, which has been around for thousands of years.

Basically, the water is just boiled and the steam is collected.

That seems like an okay way to do it. Sure, but it takes a ton of energy to boil water.

And another method, Electrolysis, uses an electric current to separate the water and the salt across a membrane.

Electricity, again, you need lots of energy.

Yeah, and the most commonly used method, reverse osmosis,

uses pressure to push water through a permeable membrane leaving the salt behind.

Sounds easy, but you actually need to create a ton of pressure to make this happen, and that also means...
